I have recently edited and animated a music vid and have exported out the final files. One for web (YouTube etc) and one for HD Broadcast (1920 x 1080 ProRes).
I have been requested to supply a file to the below specs
(SD) FILE SPECS
CODEC/CONTAINER: Apple ProRes 422/.mov
FRAMERATE/FORMAT: 25fps progressive/PAL FORMAT
RESOLUTION: 1024x576 (for standard-definition material only)
File size between 700MB - 1GB.
I cut it in Pr Pro CC and have exported it in the program itself and thru AME and I cannot get the file within the 700MB - 1GB range. I have also used Mpeg Stream Clip, Compressor 4 (just bought it before thinking that there would be more control over the data rate in the compression - not the case!) and I still cannot get the file under 1.48GB

ProRes bitrate is built into the codec. Here are your options:
- use ProRes 422 and submit a 1.48GB file
- use a lower bitrate codec to meet the file size requirement
- use ProRes 422 and cut the length of the video to reduce file size
The bitrate for ProRes 422 at 720x576-25p is listed as 41 Mbps, and it looks like your 1024x576-25p file was encoded at about 44 Mbps. If you use ProRes 422 LT with a bitrate around 28-30 Mbps the encoded file should be about 850-900MB. So then the client can decide whether they want ProRes 422 at 1.48GB or a ProRes 422 LT file that meets the size requirement.
Do a web search on "prores white paper" for more information regarding ProRes bitrates.
